Bottle-cage device for bicycles

ABSTRACT

A carrier device for a bicycle, comprises an anchoring portion, which is to be fixed to the frame, an anchoring portion, and a holding element, within which the object is introduced. The holding element changes its longitudinal axis upon introduction of the object into the holding element.

FIELD OF INVENTION

[0001] The present invention relates to a supporting device for an auxiliary article, particularly a bottle-cage device, for bicycles.

BACKGROUND

[0002] Devices of the above mentioned type are commonly used for supporting a bottle or similar container.

[0003] In most known solutions the device comprises a main body, fixed to the bicycle frame, to which there is associated a supporting part, constituted by a metal wire frame defining a housing for the bottle. When the bottle is introduced into its housing, a slight widening of the frame takes place, so that the bottle is held within the housing by the elastic reaction of the metal wire. A solution of the above mentioned type is disclosed for example in U.S. Pat. No. 5,392,971.

[0004] In known devices of the above mentioned type, the supporting part made of metal wire has a poor structural strength. With such devices, for example, the improper introduction of the bottle into the above mentioned frame may give rise to permanent deformations of the frame.

[0005] In other known solutions, an annular element within such a bottle can be inserted, in lieu of the metal wire frame, is rigidly associated to the main body of the device. To the lower end of the main body there is associated a supporting base for the bottle, whereas at the upper end of the same body a locking element is present which can be activated manually.

[0006] In use, the bottle is inserted into the annular element from above, along a direction substantially parallel to the longitudinal axis of the main body, until the lower portion of the bottle comes into abutment against the lower base. The locking element is then manually brought to a position in which it locks the bottle within the device. Withdrawal of the bottle from the device is obtained through an inverted sequence of operations with respect to those indicated above. A solution of this type is disclosed for example in U.S. Pat. No. 5,170,981.

[0007] Although this device may have greater structural strength than the previous solution, it is relatively inconvenient in use, especially while riding the bicycle, since it requires a specific manual operation by the cyclist on the locking element, in order to lock and/or unlock the bottle relative to the device.

[0008] Furthermore, the previously mentioned prior art devices are formed by a number of separate parts, which complicates the assembling of the device and the mounting thereof on the bicycle frame.

[0009] Still further, in some prior art devices the means for housing and holding the bottle in position is not an annular strip, but opposed thin, flexible curved blades or walls which hold the bottle in a jaw-like manner. In some circumstances, typically during the movement of introduction or withdrawal of the bottle with respect to its housing, the hand of the cyclist may come in contact with the edges of the reduced thickness walls or blades which may be sharp and cause injuries.

[0010] The present invention solves the previously mentioned drawbacks, and provides an accessory supporting device for bicycles, particularly a bottle cage device, which is simple to manufacture and assemble, easy to use and reliable in operation.

SUMMARY

[0011] These objects are achieved according to the present invention by an accessory supporting device for bicycles, particularly a bottle-cage device, defining a seat for housing an accessory, particularly a bottle, the device comprising an anchoring portion, which is to be fixed to the frame of a bicycle, and

[0012] a holding portion connected to said anchoring portion and defining a through axial aperture, provided for receiving the body of the accessory therethrough. The holding portion is connected to the anchoring portion and pivots, with respect to the axis of said anchoring portion, from a first position to a second position that holds the accessory in said seat.

[0013] Alternatively, the holding portion may be of relatively thin, flexible blades or walls having an edge shaped with a curved profile in cross section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

[0025] In FIG. 1, reference numeral 1 generally designates an accessory supporting device for bicycles made according to the teachings of the present invention.

[0026] The body of the device 1, preferably formed in one piece, such as of carbon fibre, comprises an anchoring portion 2, which is to be associated to the frame of a bicycle.

[0027] Substantially at the upper end of the anchoring portion 2, a supporting or holding portion 3 is provided, defining an axial passage. In the example shown, the supporting portion 3 is in the form of an annular strip, having a relative thickness of about 1.5 millimetres.

[0028] At the lower end of the anchoring portion 2, there extends orthogonally a supporting appendage 4. At the opposite end there is a tab 5 with a curved end, which depends from the edge of strip 3 above the area where it is connected to the anchoring portion 2.

[0029] In FIGS. 2 and 3, the device 1 according to the invention is mounted on a generic post 6, which typically forms part of a bicycle frame. To this end, the anchoring portion 2 has through holes for fixing screws or anchors designated by 7, which are to secure the device to tube 6.

[0030] Also in FIGS. 2 and 3, reference number 8 generally designates an article, such as a bottle, which is to be supported by the device 1. Along the periphery of bottle 8, at the upper portion thereof is a continuous groove 9 which is the point of engagement for the flexible tab 5.

[0031] Reference AF designates the axis of the annular strip 3, that is the axis of the axial passage thereof. With AS an axis is further designated, which is parallel to the longitudinal axis of the anchoring portion 2. Axis AS also represents the axis on which the bottle 8 is housed, when it is introduced down to the bottom of device 1.

[0032] According to one aspect of the present invention, the connecting portion 10 between the anchoring portion 2 and the annular strip 3 is elastically deformable or flexible. In this manner, as it will become clearly apparent in the following description, the annular strip 3 has different angular positions, depending upon whether the object 8 is present or not present within the device 1, the axis AF having a different inclination in these positions. Thus, when the bottle 8 is inserted down to the bottom of the device, the connecting portion 10 holds a portion of the inner surface of strip 3 elastically pressed against a portion of the surface of bottle 8.

[0033] In the embodiment of the invention shown in FIGS. 1-5, when the bottle 8 is not inserted into the device 1, the axis AF has a given inclination or incidence angle AI with respect to axis AS.

[0034] As it can be noted in FIGS. 3 and 4, the anchoring portion 2 has two side projections, designated by 2A on its surface opposite to that in contact with tube 6. These projections 2A extend longitudinally along portion 2 through most part of the length thereof, defining a cavity 2B.

[0035] As it will become apparent in the following, the projections 2A have the function to provide two separate supporting surfaces for the bottle 8, in order to prevent lateral movements thereof when it is inserted within the device 1 and also in order to guide the bottle 8 in its movements when it is inserted into or withdrawn from the device 1, due to the presence of cavity 2B.

[0036] The operation of device 1, in the embodiment of the invention shown in FIGS. 1-5 is the following.

[0037] The bottle 8 is introduced from above into the strip 3. As it can be noted in FIG. 2, the direction of this introduction of the bottle 8 within the strip 3 (which direction corresponds substantially to axis AF) forms a given incidence angle AI with respect to axis AS.

[0038] This means that contact of the lower portion of the object 8 with the projections 2A and the cavity 2B provides guidance for movement of the object 8. In this embodiment, the groove 9 and the tab 5 come into contact, see FIG. 5. As is illustrated in FIG. 5, the annular strip 3 is in tension against the body of bottle 8. A further holding function is provided by the action of tab 5.

[0039] Given the above mentioned incidence angle AI, during the progressive lowering of the bottle 8, the latter comes in contact both with the projections 2A and with the surface of the axial passage of strip 3. This causes an increasing urging force being applied to the body of device 1 at the connecting portion 10 between this annular strip 3 and the anchoring portion 2.

[0040] The above mentioned urging force causes the connecting portion 10 to undergo an elastic deflection, which enables a movement of the annular strip 3. This movement is such that the axis AF becomes coincident with axis AS, when the lower end of the bottle 8 comes into abutment against the lower support 4.

[0041] Since a longitudinal portion of the rounded surface of the bottle 8 is positioned within the cavity 2B, possible sideward movements of the bottle 8 are virtually prevented. The object can be withdrawn by a simple upward drawing action which causes the return of device 1 to the condition of FIG. 2.

[0042] In FIGS. 6, 7 and 8, an alternative embodiment of the invention is shown. In this embodiment, the annular strip 3 has a convex portion or projection 3A, substantially diametrically opposite to the connecting portion 10. In this embodiment, the relative positions between strip 3 and portion 2 as such that axes AF and AS as identified above, are coincident with each other. When the bottle 8 is introduced into annular strip 3 along a direction substantially parallel to portion 2, a portion of the outer surface of the bottle 8 contacts the projection 3A in a sliding motion and the lower portion of the bottle 8 contacts with the anchoring portion 2.

[0043] Also in this case, the progressive sliding downward movement of the bottle 8, in contact with projection 3A and projections 2A, causes an increasing urging action at the connecting portion 10, thus determining a movement of the annular strip 3 with respect to the anchoring portion 2. Therefore, when the lower end of the bottle 8 reaches the lower support 4, the annular strip 3 is held in tension, so that the bottle is held in position and vibrations and lateral movements thereof are virtually prevented. In this position, as shown in FIG. 6, axes AF and AS are inclined relative to each other.

[0044] Another alternative embodiment is shown with reference to FIGS. 9 and 10, in which the same reference numerals previously mentioned are used, the annular strip 3 may have a relatively constant thickness, also at its upper and lower edges, designated by 3B and 3C respectively.

[0045]FIG. 10 particularly shows how the strip 3 is shaped along its two edges 3B and 3C so as to have in cross section a profile with ends curved towards the inside of the housing for the bottle, i.e. towards the inside of the axial space defined by the annular strip 3. Alternatively, the edge 3B and/or 3C may be curved outwardly, for instance by an angle greater than 270°, to avoid potentially cutting projections.

[0046] It is to be noted that the advantages of the invention can be obtained also in case the holding means of the bottle are formed differently from a single annular strip or wall, in particular in case they are of jaw-like type, i.e. comprising a pair of opposite curved blade elements.

[0047] Finally, the upper edge of the annular strip 3 can advantageously be made with a flared shape in order to make the insertion of the bottle 8 easier.

[0048] In a similar manner, the lower supporting appendage 4 may have a curved edge, similar to what has been described and shown above with reference to the annular strip 3.

[0049] In some applications, the supporting portion 4 could be eliminated and its function accomplished by a part of the bicycle frame located below the fixing spot for the device 1.

[0050] Since the device 1 according to the invention is applicable also for supporting containers or articles other than a bottle, it should be understood that the cross-section of strip 3 could have a different shape depending upon the article which is to be supported.
